IO204: Digital I/O Module

Galvanically Isolated Digital I/O Module

The IO204 I/O module is a galvanically isolated digital input and output module with Simulink® driver blocks. The 16 digital inputs offer a 12 V or 24 V input range. The 16 digital outputs are available as high-side or low-side switches with a 6 V to 48 V output range.All channels are galvanically isolated by opto-couplers.All outputs are protected against short-circuit and thermal overload and can output up to 0.5 A per channel.

This I/O module is ideal for closed-loop controls and hardware-in-the-loop simulations using MATLAB® and Simulink.

MTBF (Mean Time Between Failure) - MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2. Environment GB 20 °C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
